BINDING MECHANISM.

Specification of Letters Patent. Patented June 1916,

' Application filed December 30, 1912, Serial No. 739,281. Renewed January 7, 1916. Serial No. 70,890.

To all whom it may concern:

Be it known that we, BERT It. BENJAMIN and CLE MA R. RANEY, citizens of the United States, residing at Oak Park and Chicago, respectively, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in B1nd1ng Mechanisms, of which the following is a full, clear, and exact specification.

Our invention relates to binding mechanisms and especially to those adapted to use in connection with grain shockers and the like.

It has among its objects to guide and osition in an improved manner the tw ne ed out from the binding needle of a binding mechanism. Y A further objectjof our invention is to deflect the twine so fed out from a binding needle in such a manner that when adapted to use in connection with a shocking machine, the twine is withdrawn from the path of a shock discharged by the shock receptacle of the shocker and so positioned with respect to that receptacle that when the first sheaf in the following shock is dellvered thereto, it will carry the twine to the bottom of said receptacle in such manner that 1t will underlie the shock subsequently built up therein.

A still further object of our invention s to draw off twine from the binding needle in such a manner that when used in connection with a shocker, the'desired amount of slack may be obtained and the tw ne may not be put under such tension as to interfere with the operation of the nachine or be' broken when it is carried down by the first sheaf in the next shock, or during the following binding operation.

e attain these objects by providing 1mproved means cooperating with the binding mechanism, which means automatically deflect the twine fed out from the binding needle as it returns from each binding op: eration and draw ofl' additional twine so that when used in connection with a shocker, the twine is held clear of a shock as the latter is discharged from the machine and in a position to be engaged by the first sheaf of the next shock and carried down thereby into the shock-receptacle, all in the desired manner and as hereinafter more fully set forth embodiment which our invention may assume in practice.

Figure 1 is a rear elevation of a shocker:

equipped with our improvement; Fig. 2 is a detail view of the twine guiding and positioning means.

In these drawings we have illustrated a shocker of the type wherein a pivoted sheafreceiving cradle ,1 normally reclines on a shocker frame 2; a binding needle 3 is automatically movable transversely across the sheaves in the cradle to cooperate with a knotter 4 to bind the sheaves into a shock, and a pivoted compressor-arm 5 cooperates with the binding needle 3 to compress the sheaves prior to the completion of the binding process.

In this construction thebinding needle 3 and compressor-arm 5 are pivoted on opposite sides of the cradle 1, and move alternately toward and away from each other in substantially parallel planes, being automatically operated from a suitable source of found that in'certain instances the tops of the sheaves carried in the cradle engage therewith as the cradle is swung about its horizontal axis to discharge the shock, thereby interfering with the operation of the mechanism and occasionally breaking the twine. It is further. foundv that an insuflicient'amou'nt of slack is" provided in the twine so that in the next binding operation, or when the first sheaf in the next shock is delivered tothe receptacle, the twine is apt to be under too great tension, with the result that it interferes with the efficient operation of the machine and is occasionally broken.

In our improvement we provide means which protrude into the path of the twine fed out from the needle 3 as the latter is returned to its normal position, and engage the twine, carrying it upward and backward out of the path of the sheaves. Obviously, this means may assume various forms. In the construction shown the twine guiding means is in the form of an arm or projection 12 carried upon a bowed resilicnt strap 13 fixed at both ends to the needle side of the compressor arm 5 and extending longitudinally thereof. This arm or projec tion 12 is preferably fixed at both ends to the strap 13 at a point between the ends of the latter, and is itself so bent or bowed that its sides form the legs of an isosceles triangle, while its peak projects angularly and to one side of the strap, as shown in Fig. 1. In a preferred form the arm or projection 12 is also formed of a round rod in order to avoid any danger of cutting or raveling the twine and to permit ready passage of the latter over the guide. Obviously, however, the twine guiding means may be made integral with the compressor arm if desired.

The operation of the device is as follows: When the compressor arm 5 is thrown down to compressing position, the binding needle 3 is likewise lowered into its down or binding position, the parts assuming the position shown in full lines in Fig. 1. In this position the twine is clear of the guide 12. At the completion of the binding process the binding needle and compressor arm are automatically returned substantially simultaneously to the up or dotted line position shown in that figure. The twine guide 12 then moves upward with the compressor arm under the twine fed out from the needle and raises the same to the dotted line position shown, wherein it is held out of the path of the sheaves in the cradle 1 as the latter is swung about its pivot to shock discharging position. It is here to be noted that as the twine guide is thus swung upward it automatically draws off an additional amount of twine, and thus, at the same time,-insures the requisite amount of slack for the next binding operation. It is further to be noted that the twine is thus also positioned transversely with respect to the cradle and above the latter so that it can be carried down to the bottom thereof by the first sheaf in the next shock, the twine being readily disengaged from the twine guide when pulled downward by that sheaf and ample slack being provided so that no interference with the operation of the mechanism may result. Obviously, when the parts are again brought into compressing and binding position, since the twine is thus automatically disengaged from the projection there is no interference With the binding process.

parting from the spirit of our invention.
